Name the central angle of the given arc.
What is the independent and dependent variable in this problem?
Answer:
The height (h) of the ball is termed as the dependent variable and the time (t) is called the independent variable.
Step-by-step explanation:
We know that the function
y = f(x)
where y is a function of x.
Here:
The input variable 'x' is called the independent variableThe output variable 'y' is called the independent variable because the value of output y depends upon the value of the input 'x'.Given the function of the height of the ball as a function of time is modeled by the equation
h(t) = -16t² + 90t + 5
As the height of the ball depends upon the time as the height of the ball is a function of time.
Thus, the height (h) of the ball is termed as the dependent variable and the time (t) is called the independent variable.

Tommy makes $200,000 per year. Tommy's monthly taxes are 10% for Federal Income Tax, 4.2% for Social Security Tax, 1.75% for Medicare Tax, and 0.5% for Local Taxes. What is Tommy's monthly Take Home Pay?
Answer: $13,925
Step-by-step explanation:
Tommy makes $200,000 per year.
He then has to pay taxes of 10% for Federal Income Tax, 4.2% for Social Security Tax, 1.75% for Medicare Tax, and 0.5% for Local Taxes.
His total taxes are therefore:
= 10% + 4.2% + 1.75% + 0.5%
= 16.45%
Taxes in dollars are:
= Monthly salary * taxes
= (200,000/12 months) * 16.45%
= $2,741.67
Monthly take home pay:
= Monthly salary - monthly tax
= 200,000 / 12 months - 2,741.67
= 16,666.67 - 2,741.67
= $13,925
The area of a rectangle is at most 400 square centimeters. Write an inequality to represent the possible values for the height, h, for the height. The length is 16cm for one side
Answer:
1ft≤h≤25ft
Step-by-step explanation:
The area of a rectangle is expressed as;
Area = Length * height
A = Lh
If the area of a rectangle is at most 400 square centimeter, this is expressed as;
A ≤400
≤ means at most i.e it can not be greater than 400
Lh ≤ 400
Given L = 16
16h ≤ 400
h ≤ 400/16
h ≤ 25
Hence the possible values of the height are with the range 1ft≤h≤25ft since the dimension can not be negative

Answer:
a. [tex]s^2 - \frac{1}{4}s^2\pi[/tex]
b. [tex]100-25\pi[/tex]
Step-by-step explanation:
The shaded area is the area of the square minus the area of the circle, so it is [tex]s^2 - \frac{1}{4}s^2\pi[/tex], because s is the diameter of the circle. Filling in s = 10 gives us that the shaded area equals [tex]100-25\pi[/tex].

Jan walks 2 miles at a constant rate of 3 miles per hour and then runs 1 mile at a constant rate of 8 miles per hour.
(a) What is Jan’s average speed for the entire trip?
(b) Is the average speed in part (a) equal to the average of Jan’s two speeds?
Answer:
(a).4.36 mph
(b) No
Step-by-step explanation:
We are given that
Jan covered distance,s1 =2 miles
Speed of Jan, a=3 mph
s2=1 mile
b=8mph
a.
We have to find the Jan' s average speed for the entire trip.
Average speed =[tex]\frac{2ab}{a+b}[/tex]
Using the formula
Average speed=[tex]\frac{2(3)(8)}{3+8}=4.36mph[/tex]
b.
Average speed with two speed
Average of Jan’s two speeds
[tex]=\frac{a+b}{2}[/tex]
=[tex]\frac{3+8}{2}=5.5 mph[/tex]
[tex]4.36\neq 5.5[/tex]
Hence, the average speed in part (a) is not equal to the average of Jan’s two speeds.

Answer:
c must be -4
Step-by-step explanation:
x^2 - 5x + c = 0 is a quadratic whose coefficients are a = 1, b = -5 and c = c.
The discriminant is b^2 - 4ac, and we know that b^2 - 4ac = 41.
Substituting -5 for b and 1 for a, we get:
(-b)^2 - 4(1)(c) = 41, or 25 - 4c = 41, or -4c = 16. Thus, c must be -4, and the quadratic is
x^2 - 5x - 4
